      CPU and System Topology

      Server Description

      An Intel-powered virtual machine featuring high memory density and strong uncached memory bandwidth for memory-intensive enterprise applications.

      Memory OptimizedGeneral Purpose

      Microsoft Azure E48s_v4 is an ESv4-family virtual machine configured with 48 dedicated vCPUs and 384.0 GB of RAM, establishing an 8.0 GB per core memory-to-vCPU ratio. Powered by an Intel Xeon 8370C processor running at 2.8 GHz, this x86_64 server utilizes the Microsoft Hyper-V hypervisor. It lacks local storage and GPUs but supports Premium Storage. Performance benchmarks show strong uncached memory bandwidth, with large-block reads at 250.5 GB/sec and writes at 126.78 GB/sec. However, single-threaded decompression and large-model LLM inference represent performance tradeoffs, scoring in the bottom 25 percent. With average scores in database operations and Redis throughput, this memory-optimized server is suited for memory-intensive enterprise applications, relational databases, and caching workloads.

      Workload Profiles

      2Score
      Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
